EIGER. I. [OIII]-emitting galaxies at 5.3<z<6.9
Listed in IVOA Registry (Virtual Observatory)
Description
We present a first sample of 117 [OIII]{lambda}{lambda}4960,5008 -selected star-forming galaxies at 5.33<z<6.93 detected in JWST/NIRCam 3.5{mu}m slitless spectroscopy of a 6.5'x3.4' field centered on the hyperluminous quasar SDSS J010013.02+280225.8 (SDSSJ0100+2802), obtained as part of the Emission-line galaxies and Intergalactic Gas in the Epoch of Reionization (EIGER) survey. Three prominent galaxy overdensities are observed, one of them at the redshift of the quasar.
Galaxies are found within 200pkpc and 105km/s of four known metal absorption-line systems. We focus on the role of the galaxies in ionizing the intergalactic medium (IGM) during the later stages of cosmic reionization and construct the mean Ly{alpha} and Ly{beta} transmission as a function of distance from the galaxies. At the lowest redshifts in our study, 5.3<z<5.7, the IGM transmission rises monotonically with distance from the galaxies, as seen previously at lower redshifts.

In contrast, at 5.7<z<6.14, the transmission of both Ly{alpha} and Ly{beta} first increases with distance but then peaks at a distance of 5cMpc before declining. Finally, in the region 6.15<z<6.26, where the additional ionizing radiation from the quasar dominates, the monotonic increase in transmission with distance is reestablished. This result is interpreted to represent evidence that the transmission of the IGM at z~5.9 toward J0100+2802 results from the "local" ionizing radiation of galaxies that dominates over the much-reduced cosmic background.
